The purpose of this study is to determine how the overall factors of gait are affected by the development of the lower triceps. The subjects of the study were 10 adults in their 20s or older based in D, who had no physical diseases and no musculoskeletal problems, and compared and analyzed pedestrian variables by dividing them into upper and lower groups according to differences in lower limb muscle groups. The results of this study are as follows. First, the correlation between the quality of the lower extremity muscle and the gait mechanism showed no significant difference in other variants of gait, but a significant difference in right foot stride time (p<.05). Second, there was no significant difference in the correlation between muscle strain of the lower extremity and the gait mechanism, which is all related to gait. The above results showed that lower extremity muscle development affects walking in the same way as previous studies, but the results did not show significant differences, resulting in differences from previous studies. This can be inferred as a result of no significant difference in young age in their 20s as there has yet to be a near-decrease and the body is healthy. Muscular tension in the lower extremity muscles is also not associated with gait, and an important part of the gait mechanism is believed to affect muscle mass and other areas, regardless of muscle tension and stiffness. In future studies of gait mechanisms, it is hoped that research will continue to identify the impact of gait according to physical characteristics and explore the diversity of gait training through physical instrumentation.

본연구는 아동청소년 바우처사업의 효과성을 연구하고자 하며, 12주 기초체력을 중심으로 바우처집단과 일반집단을 비교 분석하는 것에 목적을 두었다. 이를 위해 D광역시 S구 소재의 L스포츠바우처사업 센터에서 참여아동청소년을 편의표본추출법을 사용하여 15명의 학생을 추출하였고, 바우처사업에 전혀 참여하지 않은 아동청소년을 별도로 15명의 학생을 추출하여 총 30명의 아동청소년을 비교 분석하였다. 연구의 목적을 달성하기 위하여 바우처집단(n=15), 일반집단(n=15)을 설정한 다음 12주간 바우처프로그램 유무를 통해 각각의 바우처집단과 일반집단을 통하여 집단 간의 차이점을 규명하였다. 이상과 같은 연구방법과 연구모형 검증을 기초로 하여 이 연구에서 도출된 결과는 다음과 같다. 첫째, 근지구력의 경우 바우처집단(-2.751, p<.05), 일반집단(-2.750, p<.05) 모두 사전사후검사에서 유의미한 차이가 나타났다. 둘째, 평형성의 경우 일반집단(-3.372, p<.01)에서만 사전사후검사에서 유의미한 차이가 나타났다. 셋째, 순발력의 경우 바우처집단(-2.746, p<.05)에서만 유의미한 차이가 나타났다. 넷째, 유연성의 경우 일반집단(-3.108, p<.01)에서만 사전사후검사에서 유의미한 차이가 나타났다. 다섯째, 민첩성의 경우 바우처집단(4.658, p<.001)에서만 사전사후검사에서 유의미한 차이가 나타났다. 여섯째, 근력의 경우 바우처집단(-2.574, p<.05), 일반집단(-4.826, p<.001) 모두 사전사후검사에서 유의미한 차이가 나타났다. 이상의 결과를 종합하면 아동청소년 바우처사업의 효과성에서 종합적으로 살펴보았을 때 근지구력, 순발력, 근력영역에서 바우처사업의 효과가 있는 것으로 나타났다. 결론적으로, 현 바우처사업의 프로그램은 아동청소년의 기초체력향상에 큰 도움이 되지 않고 있음을 의미한다. 바우처사업 뿐만 아니라 정부 정책 대다수가 성과 위주의 양적 사업을 권장하고 있다. 이에 대다수의 아동청소년들이 바우처사업에 참여할지는 모르겠으나, 성장기 아동청소년의 실질적인 체력요소에는 정책이 미치지 못하는 점을 헤아려 정책을 운영하길 고대한다. This study aims to study the effectiveness of child and youth voucher projects and to compare and analyze vouchers and general groups with 12-week fundamentals. To this end, 15 students were selected using the Convenience Sample Extraction Act for participating children at the L Sports voucher business center in S-gu, D-City. and 15 students were selected separately for non-participation in voucher projects, and a total of 30 children were compared and analyzed. In order to achieve the purpose of the study, the difference between groups was identified through the presence of the voucher program for 12 weeks after establishing voucher groups (n=15) and general groups (n=15). Based on the above-mentioned methods and verification of the study model, the results obtained from this study are as follows. First, for muscle endurance, the voucher group (-2.751, p<.05), General group (-2.750, p<.05) All pre-post examinations showed significant differences. Second, for equilibrium, general group (-3.372, p<.01) did the pre-post examination show a significant difference. Thirdly, for pure stroke, the voucher group (-2.746, p<.05) showed significant differences. Fourth, for flexibility, general group (-3.108, p<.01) did the pre-post examination show a significant difference. Fifth, for agility, the voucher group (4.658, p<.001) showed significant differences in pre-post examinations. Sixth, for muscle strength, the voucher group (-2.574, p<.05), General group (-4.826, p<.001) All pre-post examinations showed significant differences. When combined with the above results, a comprehensive review of the effectiveness of the voucher business for children and adolescents shows that the voucher business has an effect in the areas of muscle endurance, pureness and muscle strength. In conclusion, the current voucher program is not very helpful for improving the basic fitness of children and adolescents. Not only the voucher project but also the majority of government policies encourage performance-oriented quantitative projects. While it is not clear whether the majority of children will participate in the voucher business, we look forward to running the policy considering that the policy falls short of the actual physical factors of growing children.

The purpose of this study is to compare and analyze the effects of 12-week Plyometric Training and core training on physical composition and basic physical strength of university students. The study subjects were 18 university students from G City G University, who conducted each 12-week training session, and then compared and analyzed the Plyometric Training Group(n=9) and the Core Training Group(n=9). The main results from this study are as follows. First, Plyometric training and core training show significant time differences in weight (F=4.692; p<.05) Second, Plyometric training and core training show significant time differences in BMI (F=6.854, p<.05) Third, the results of Plyometric training and core training show significant time differences in muscle endurance(F=25.953, p=.05), fourth, Plyometric training and core training show significant time differences in agility (F=10.316, p<.05). To sum up the above, each 12-week training could produce a significant effect between periods, but the training could not show the superiority of a particular training because there was no significant difference between the training groups. This is judged that customized training through composite training can be more accurate and effective exercise rather than specific training, considering the principle of training, especially specificity and individuality, and it is expected that this will be a useful theoretical basis for improving the health of university students in the future.

HCMV remains the most common congenital virus infection in the world. Although the majority of congenital HCMV infections occur silently, 5% to 10% of infected newborns exhibit signs of HCMV disease in the neonatal period. Clinical manifestations include jaundice, hepatosplenomegaly, intrauterine growth retardation, microcephaly, petechial or purpuric rash, chorioretinitis, or pneumonitis. Common laboratory abnormalities in congenital HCMV infections include thrombocytopenia, anemia, hyperbilirubinemia, and elevation in serum hepatic transaminase levels. The CSF may show elevated protein content or pleocytosis. Neuroimaging studies reveal a variety of CNS abnormalities ranging from lissencephaly to multicystic encephalomalacia. Intracranial calcifications, usually periventricular, can be identified in 25% to 50% of symptomatic infants. We experienced one case of congenital CMV infection related infantile spasm. On examination at admission at 4 months of his age, he had facal seizure, microcephaly, and increased muscle tone and DTR. Brain CT revealed multiple periventricular calcification. He had EEG finding compatible with partial sezure. Seizure activity was controlled by ACTH therapy

White matter injury following rotavirus infection in neonates: new aspects to a forgotten entity, ‘fifth day fits’?

염정숙,박찬후 대한소아청소년과학회 2016 Clinical and Experimental Pediatrics (CEP) Vol.59 No.7

That rotavirus infection can cause neurological symptoms in young children has been well established. However, it is surprising why rotavirus infection has been overlooked as a cause of neonatal seizures for many years, despite significant research interest in neonatal rotavirus infection. Neonates are the age group most vulnerable to seizures, which are typically attributed to a wide range of causes. By contrast, because rotavirus infection is usually asymptomatic, it has been difficult to identify an association between this virus and neonatal seizures. The conventional wisdom has been that, although neonates are commonly infected with rotavirus, neurological complications are rare in this age. However, recent studies using diffusion-weighted imaging (DWI) have suggested a connection between rotavirus infection and neonatal seizures and that rotavirus infection can induce diffuse white matter injury without direct invasion of the central nervous system. The clinical features of white matter injury in rotavirus-infected neonates include the onset of seizures at days 4–6 of life in apparently healthy term infants. The recent findings seem to contradict the conventional wisdom. However, white matter injury might not be a completely new aspect of rotavirus infection in neonates, considering the forgotten clinical entity of neonatal seizures, ‘fifth day fits’. With increased use of DWI in neonatal seizures, we are just starting to understand connection between viral infection and white matter injury in neonates. In this review, we discuss the historical aspects of rotavirus infection and neonatal seizures. We also present the clinical features of white matter injury in neonatal rotavirus infection.

저자들은 폐형성부전과 다발성 선천성 기형을 가지고 있는 생존 출생아에서 말초혈액의 염색체 검사 및 FISH로 확인된 trisomy 22 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. We report a case of trisomy 22 in a liveborn male infant which was confirmed by fluorescence in situ hybridization(FISH), macrocultures and GTG-banding, and RHA-banding procedures of peripheral white blood cells. The infant showed lung hypoplasia, which is a unique presentation, with other clinical manifestations of previously reported cases of trisomy 22, such as intrauterine growth retardation, cleft palate, micrognathia, large atrial septal defect, limb anomalies, imperforate anus, and hypospadias. Our report gives weight to the previously reported observation that pulmonary hypoplasia may be associated in trisomy 22.

Primary peritonitis usually refers to a bacterial infection of the peritoneal cavity without a demonstrable intra-abdominal source. Most cases occur in children with ascites resulting from nephrotic syndrome or cirrhosis. Rarely, it may occur in previously healthy children less than 7years of age, usually a girl. Distinguishing primary peritonitis from appendicitis may be impossible in patients without a history of nephrotic syndrome or cirrhosis. Accordingly, the diagnosis of primary peritonitis is made only at laparotomy. We report one case of primary pneumococcal peritonitis in a 27-month-old female who underwent explorative laparotomy to discover the cause of suspicious intestinal perforation and mechanical ileus. Later, pneumococci were cultured in blood and gram-positive diplococci were isolated from the pus of peritoneal cavity.
